  You can use whatever calling convention you want when calling
managed methods, but
the JIT needs to support calling native functions as well. Most
architectures pass
structures on the stack when calling managed methods, and implement
the platform ABI
when calling native methods.

As for the second question: In mini_init (), there are some calls
which can be commented
out if your JIT is not yet able to run some managed code, like
Crashing in InitializeArray () usually means problems with handling
ldtoken etc.
